Minimum motor rotation frequency (Pr.13)
<IPM>
The above parameters can be set when
Pr.160 Extended function display selection
= "0."
* The value after the IPM parameter initialization.
Set the frequency where the motor starts running.
Set the deadband in the low-speed range to eliminate noise and offset deviation when setting a frequency
with analog input.

(180r/min)

0 to 60Hz
The frequency where the motor starts
running can be set in the range of 0 to
60Hz.
The frequency where the IPM motor starts running can be set
in the range of 0 to 60Hz.
While the frequency command is less than the
Pr. 13 Starting
frequency
setting, the IPM motor is stopped.
When the frequency command reaches the set frequency or
higher, the IPM motor accelerates according to the
Pr. 7
Acceleration time setting.
REMARKS
Under general-purpose motor control (under V/F control and Simple magnetic flux vector control), the inverter starts output at
the frequency set in
Pr.13
at start, but in IPM motor control, the inverter always starts output from 0.01Hz.
NOTE
The inverter output does not start when the frequency-setting signal is less than
Pr.13
.
For example, while
Pr.13
= 20Hz, the inverter output starts when the frequency setting signal reaches 20Hz.
CAUTION
Note that when
Pr. 13
is set to any value lower than
Pr. 2 Minimum frequency
, simply turning ON the start signal
will run the motor at the preset frequency even if the command frequency is not input.
